Review of Trash fuel by 97 percent'0. The EPA rule was the most significant mobile <br />ll <br />ti <br />C source initiative since the 1970 Clean Air Act Amendments <br />on <br />o <br />ec establishing the U.S. Mobile Source Emission Control Program. <br />~ X71 acfis <br />p Beginning with the 2007 model year, 100 percent of the on-road <br /> diesel heavy duty engines {HDEs} are required to use a diesel <br /> particulate filter and 50 percent of the engines are required to use <br /> nitrogen oxide {NOx} exhaust control technology. Beginning with <br /> the 2010 model year, 100 percent of the on-road heavy-duty <br /> diesel engines will require NOx exhaust technology. <br /> Figure 2 below provides an illustration of the improvements in <br /> engine emissions that have occurred aver the last 25 years. With <br /> the 2010 standards the emissions from model year 2010 HDE's <br /> will be a small fraction of what they were less than 10 years ago. <br /> Figure 2 <br /> Emission Standards Time Line <br /> ,, <br /> <br /> % ~g~` <br />~ RA <br /> Sl LFiYi~ <br />1 <br />~..~ <br /> ~~ ~ 2f102 <br />[[ <br /> ?S <br /> ~ <br /> z ~ti~~ b~ ~~~~ <br />_ is " <br /> <br /> ~p~tiit~r St,~:n:~arei <br />~~~~~'i~' Period <br /> O~ ~ 3010 <br />OA _ <br /> Q~ RO3 a.iQ <br /> P~TIQELATE [g/HP~r] <br /> Source: http:llwww.cumminswestport.comlproductslemissions.php <br /> It is important to understand, however, is that these standards <br /> apply to engine manufacturers and not to fleet operators. There <br /> are no requirements that fleet operators, including trash haulers, <br /> comply with the standards within any specific time period. Relying <br /> 10 As of 2006, refiners and importers nationwide are required to ensure <br /> that at least 80% of the volume of the highway diesel fuel they produce <br /> or import is ultra low sulfur diesel. {ULSD) compliant. By 2009 95% a€ <br /> diesel fuel will have a sulfur limit of 15 parts per million {ppm). By <br /> December 1, 2010 100% of the diesel fuel sold will need to meet that <br /> limit. ULSD fuel enables the use of cleaner technology diesel engines <br /> and vehicles with advanced emission control devices, resulting in <br /> <br />significant improved air quality <br />Section 2 - 8 <br />
